Abstract

The invention discloses a graphene composite cable material and a method for preparing the same. The graphene composite cable material is made of polyimide emulsion, modified montmorillonite, high-density polyethylene, polyfuran dioctyl phthalate glycol ester, silane coupling agents KH-550, sulfur powder, titanium diboride, glass fibers, citrate, graphene, choline alfoscerate, di-(3, 4-dimethyl) benzyl sorbitol, dispersing agents and anti-aging agents. The method includes processes of fitting grinding, spray-drying, acidifying, mixing, ultrasonic treatment, extrusion, stretching, heat setting and the like. The graphene composite cable material and the method have the advantages that requirements of high-voltage and direct-current power transmission cables on the hardness and the toughness of the graphene composite cable material prepared by the aid of the method can be met, the graphene composite cable material is good in environmental protection performance and low in integral cost, accordingly, industrial requirements can be met, and the graphene composite cable material and the method have excellent application prospects.

Description

technical field [0001] The invention relates to the technical field of composite graphene materials, in particular to a graphene composite cable material and a preparation method thereof. Background technique [0002] Cable material is a general term for plastics used for wire and cable insulation and sheathing. It is made of rubber, plastic, nylon and other materials as base materials, combined with auxiliary components such as plasticizers, fillers, color masterbatches, and antioxidants. Different types of cables and The use environment has different requirements on the performance of cable materials. [0003] HVDC transmission technology has developed rapidly in recent years and is mainly used in renewable resource grid connection, island power supply, submarine cables and urban underground cables. Moreover, DC transmission can connect unstable power sources such as solar power generation and wind power generation with the power system, which has more advantages than AC ...
